It was clipping the daily challenge completion checkmark, and it
originates in some veeeeery old code where the profile overlay looked
and behaved very differently (0fa0271878).
With the animation logic being external, it was going to make it very
hard to apply the scroll offset when a new panel is added or removed
before the current selection.
There's no real reason for the animations to be local to beatmap
carousel. If there's a usage in the future where the animation is to
change, we can add more customisation to `Carousel` itself.
